Guanajuato Silver Company Ltd. (TSXV: GSVR, OTCQX: GSVRF) is adding a thrilling new chapter to the 500-year mining story of central Mexico. The company has just reported that its latest drilling at the historic Valenciana Mines Complex, specifically the Santa Margarita zone, has uncovered gold intercepts that are among the highest in recent memory, setting the stage for the development of a new mining block next year.
The standout results from the Santa Margarita drilling include two impressive intercepts: a true width of 0.98 metres grading 16.7 grams per tonne (g/t) gold and 12g/t silver (1,432g/t silver equivalent), and a narrower but richer interval of 0.26 metres with 45.3g/t gold and 38g/t silver (3,886g/t silver equivalent). These figures are not just incremental gains. They represent a notable jump above the historical average gold values for Valenciana, suggesting that the Santa Margarita area could soon become a key source for high-quality, production-ready material.
James Anderson, Chairman and CEO, sees these outcomes as a testament to the enduring potential of Valenciana, remarking that the mine’s centuries-old legacy is far from finished. He points to the most recent drill program as proof that new, economically significant material remains to be found, especially at Santa Margarita, which has produced these latest intercepts that will be central to the next phase of development in 2025.
The company’s exploration program in the first quarter of 2025 drilled approximately 475 metres across both the Santa Margarita and Maravillas zones at Valenciana. While the focus has been on Santa Margarita, the Maravillas area, historically overlooked, also turned up a wide vein, with hole UGM25-001 intersecting a 7.06-metre stretch containing moderate mineralization. More drilling is in the pipeline for Maravillas in the hope of expanding the known footprint and chasing after other potential high-grade shoots.
It’s not just about numbers. The process behind these results has involved rigorous procedures that gold industry insiders would recognize as exceeding standard regulatory norms. Every step, from core sampling by in-house geologists to secure transit and lab work, is documented and overseen, with about 20% of samples sent to fully independent, ISO-certified laboratories for validation. The company’s local laboratory at the Valenciana site does most of the testing, but external labs in Silao and Hermosillo provide a further layer of quality assurance. As of this announcement, third-party verification of the most recent samples is still pending, but the company’s sampling process has so far stood up to careful review by Guanajuato Silver’s Qualified Person, William Gehlen. According to Gehlen, no red flags were found in the technical data or in the QA/QC checks that could seriously undermine the reported drilling results.
Guanajuato Silver’s broader story is also worth noting. The company, headquartered in Vancouver but operating exclusively in Mexico, has established itself as a fast-growing producer of silver and gold concentrates. Beyond Valenciana, it runs mining operations at El Cubo, San Ignacio and Topia, with four mines and three processing facilities across two states, Guanajuato and Durango. This growth is notable in a region with nearly five centuries of continuous mining, cementing Guanajuato Silver’s place as a significant name among Mexico’s precious metals producers.
One unique twist for investors and market watchers: while Guanajuato Silver’s operations are all in Mexico, the company reports in US dollars and most result headlines focus on gold and silver grades, rather than headline dollar values. This keeps the spotlight firmly on what matters most to miners, how much metal is in the ground, and how efficiently and reliably it can be brought out.
With high-grade gold and silver intercepts now confirmed at Santa Margarita and further investigative drilling scheduled, Guanajuato Silver is making a strong case that even after five hundred years, Valenciana’s best days might still be ahead of it.
